In high altitude astronomy, it is time for the old guard to be replaced with new blood that fully understands the law, health and safety, and the full range of toxicity that astronomical observatories present to their workers.

At the age of 45, most days in Tucson were spent feeling like I was on the summit of Mauna Kea, as I was exhibiting debilitating health symptoms that corresponded to what I saw at very high altitude. I was later to find that I had erratic low blood oxygen levels after almost a decade of high altitude work.

After a decade of working in high altitude astronomy the medical profession discovered that I had a hole in my heart, erratic low blood oxygen levels and brain issues. Heart, lung and brain problems appear to be long term known adverse health aspects of high altitude work and unnatural electromagnetic radiation exposures.

Workers should refuse to work in any environment that depresses their blood oxygen levels below 92% SpO2.

The closer you get to the Sun, the lower your blood oxygen levels go.

In the future, it may turn out that fossil fuels are the blood of the Earth and by extracting them may lead to serious consequences to the Earth's survival, and by association, that of the humans.

There is no shortage of dead people in graveyards that got there through blood clots.

My Electromagnetic Hypersensitivity (EHS) appeared to be caused by blood clots in the brain which had to be flushed out to cure it. The mystery was why I had the blood clots there, which recently was solved by the medical profession as I have a hole in my heart that creates them. It is estimated that 25% of the population have a hole in their heart and Atrial Septal Defect (ASD) may be one of the triggers for the onset of EHS in a person.

Hazardous low blood oxygen levels in high altitude workers is a dirty secret of professional astronomy.
